title

Highly Automated Control of a Motor Vehicle The invention relates to the highly automated control of a motor vehicle. In particular, the invention relates to interaction with an authorized entity such as a police force.

By means of a highly automated function (HAF), a motor vehicle can be guided independently of the driver. In particular, a longitudinal or lateral control of the motor vehicle can be performed without the driver having to exercise further control of the function performed. Since the driver is not available as a fallback level in the event of an unknown situation or malfunction, HAF functions must be implemented so that the motor vehicle is always in a safe condition.

Some situations can be difficult to capture for an automated system. For example, a lateral control of a motor vehicle may make use of lane markings that are optically scanned, for example. However, for example, if a police officer intervenes in the traffic control system, it is generally difficult for a processing system to correctly capture the policeman and the driving instruction he uses, for example by means of a hand signal, based on optical data.

DE 10 2010 003 740 A1 therefore proposes to transmit an instruction from a police emergency vehicle to another motor vehicle, for example by means of data radio.

The invention has for its object to control a motor vehicle by means of highly automated functions when an authorized body in to ensure traffic. The invention solves this problem by means of the subject matters of the independent claims. Subclaims give preferred embodiments again.

Disclosure of the invention

A method for controlling a motor vehicle comprises steps of driving the motor vehicle independently on a road, receiving a wirelessly transmitted driving instruction from a device in an environment of the motor vehicle, outputting an indication of the driving instruction to a driver of the motor vehicle, determining that Driver has not taken over the driving of the motor vehicle for more than a predetermined time, and the driver-independent execution of the driving instruction.

As a result, the driver-independent driving of the motor vehicle can also be continued if, for example, an order force gives a driving instruction to the motor vehicle. For example, the enforcement force may be a police force, a field fighter, the Federal Office for Freight Traffic, Customs, the Fire Department, the Federal Agency for Technical Relief or an emergency medical service.

As a result, the driving instruction can be quickly followed, in particular, if the driver is unable to respond to the driving instruction within a reasonable time. The safety of the driving operation of the motor vehicle and a surrounding road traffic can be ensured thereby improved.

In one embodiment, the device is stationary relative to the road. For example, a police officer may carry the device with him. Optical characters, which are usually issued to drivers of motor vehicles, can be completed by wireless signs to highly automated guided vehicles.

In another embodiment, the device is mounted on board a preceding or following vehicle. The vehicle may be a civilian vehicle that initially can not be visually recognizable as an emergency vehicle. However, it may also be an official emergency vehicle, which is equipped for example with an optical stop signal generator. In one embodiment, the driving instruction comprises following the further motor vehicle. In this case, the motor vehicle may be controlled to follow the preceding vehicle. A safety distance to be maintained can be selected independently of the driver.

In another embodiment, the instruction includes granting the right of way of the other vehicle. The motor vehicle can be controlled to indicate the granting of the right of way by driving maneuvers. This may include, for example, throttling the speed, driving on the right-hand edge of the track or switching on a lighting of the motor vehicle.

In yet another embodiment, the instruction includes stopping the motor vehicle. In this case, the motor vehicle can first select a favorable stopping line, for example a hard shoulder, a holding bay, a driveway or a parking space. If a favorable location can not be found, it may either be rolled out slowly or the motor vehicle may be controlled to follow a vehicle from which the driving instruction has been transmitted. In yet another embodiment, the driving instruction includes forming a rescue lane. The motor vehicle can be controlled to control a right or left edge of the road to clear the escape route. The choice of the road edge can be made dependent on a used lane, a maneuver of a surrounding vehicle or a default.

In yet another embodiment, an acknowledgment of the driving instruction is sensed by the driver and the guidance of the motor vehicle is handed over to the driver. This transfer can in principle take place at any point in the procedure. In a variant can be monitored after passing the leadership of the motor vehicle to the driver, whether the driver complies with the driving instruction. If he does not do so, then another signal can be issued to the driver. A signal may also be sent back to the device in the vicinity of the motor vehicle, which also includes the driver's refusal to execute the driving instruction. The driver's guidance can be transmitted to the location from which the driving instruction was received. As a result, for example, a police officer who has transmitted the driving instruction can better estimate who is currently controlling the motor vehicle.

The received travel instruction can be acknowledged at the sending station. The sending body can thus assume legally that the driver has been informed of the transmitted driving instruction.

Both feedback may be relevant in terms of laws, insurance and general documentation.

A computer program product comprises program code means for carrying out the method described above when the computer program product runs on a processor or is stored on a computer-readable medium.

A control device for a motor vehicle is adapted to guide the motor vehicle driver independently on a road and comprises a receiving device for receiving a wirelessly transmitted driving instruction from a device in an environment of the motor vehicle and an output device for outputting an indication of the driving instruction to a driver of the motor vehicle , In this case, the control device is further configured to execute the driving instruction independently of the driver if the driver has not taken over the driving of the motor vehicle for longer than a predetermined time.

Detailed description of embodiments

1 shows a motor vehicle 100 with a control device 105 for the driver-independent guidance of the motor vehicle 100. The control device 105 comprises a processing device 107 and is adapted, in particular a longitudinal or lateral control of the motor vehicle 100 without the intervention of a driver and in particular without the possibility requiring rapid delivery of control of the motor vehicle 100 to the driver. In the illustrated exemplary embodiment, the controller 105 is connected to a wheel 110 to steer or brake it. Furthermore, the control device 105 is connected in an exemplary manner to a drive motor 15 in order to control an acceleration of the motor vehicle 100.

The control of the longitudinal or transverse movement of the motor vehicle 100 is usually carried out as a function of a control target, which can be adopted for example from a navigation system, and control parameters that can be sampled from an environment of the motor vehicle 100. Representing a variety of different possible sensors, a camera 120 for optical scanning of the environment of the motor vehicle 100 is located. In other embodiments, for example, radar, lidar or ultrasonic sensors may be used.

Furthermore, the control device 105 comprises a receiving device 125 for receiving a wirelessly transmitted driving instruction from a device 130 in the vicinity of the motor vehicle 100. The device 130 may comprise, for example, a portable hand-operated device or in another embodiment also on board a vehicle 135 be arranged. The

Use of the device 130 is usually restricted to an area around the motor vehicle 100 that an operator of the device 130 can view. The wireless transmission between the device 130 and the motor vehicle 100 may be, for example, by means of WLAN, Bluetooth, mobile radio, infrared or generally vehicle-to-vehicle (car-to-car, C2C) or vehicle-zu¬

Infrastructure (Car-to-Infrastructure, C2I). From the device 130, a driving instruction can be transmitted to the motor vehicle 100, which can alternatively be implemented by the driver of the motor vehicle 100 or by the control device 105. It is preferred that the driving instruction is transmitted in encrypted form. In addition, the driving instruction may include an identification of the motor vehicle 100, for example, its registration number. Furthermore, an identification of a bedperson, an organization or the further vehicle 135 can be transmitted. The controller 105 may be configured to wirelessly return an acknowledgment of receipt of the driving instruction to the device 130. This confirmation also preferably takes place on an encrypted connection and may include identifications of the motor vehicle 100 and / or the device 130.

The confirmation may be returned automatically or under the control of the driver of the motor vehicle 100.

It is preferred that the control device 105 informs the driver of the motor vehicle 100 of an incoming driving instruction by means of an output device 140. For this purpose, the driving instruction can be output acoustically, for example as a spoken text or as a signal tone. In addition or alteratively, an optical output can also be provided, for example as instruction text or as a symbol.

The control device 105 is preferably set up to automatically implement a received driving instruction if the driver does not take over the motor vehicle 100 for more than a predetermined time and / or the driver does not implement the driving instruction for longer than a predetermined time.

FIG. 2 shows a flowchart of a method 200 for controlling the motor vehicle 100 of FIG. 1. The method 200 is set up in particular for running on the processing device 107 of the control device 105.

In a first step 205, the motor vehicle 100 is guided independently of the driver. The guiding can in particular be a longitudinal and / or transverse control of the force Cover vehicle 100 on a street. In a step 210, a wirelessly transmitted driving instruction is received. In one embodiment, an acknowledgment of the received driving instruction may be returned. Furthermore, in a step 215, an indication of the driving instruction is output to the driver of the motor vehicle 100.

In a step 220 it is checked whether the driver takes over the leadership of the motor vehicle 100. This can be done for example by operating an input component such as a button or by actuating a control component such as a gas or brake pedal, a steering wheel or a gear selector lever. In this case, in a step 225, the guidance is transferred via the motor vehicle 100 to the driver. If the driver takes over the guidance of the motor vehicle 100, then this circumstance can be transmitted back to the component from which the driving instruction was received. In one embodiment, it may also be communicated that the driver has not (yet) taken over the guidance.

On the other hand, if it is determined in step 220 that the driver does not take the lead, then after a lapse of a predetermined time in a step 230, the received driving instruction can be executed independently of the driver. For example, as detailed above, the driving instruction may include following the other vehicle 135, granting the right of way of the other vehicle 135, stopping the motor vehicle 100, or forming a rescue lane.

In another embodiment, the driver may also speed up the transition from step 220 to step 230 by giving his consent to execute the received driving instruction, for example, by actuating a predetermined switch or button.

The control device 105 of Figure 1 and the method 200 of Figure 2 are adapted to automatically handle an intervention of an authorized person in the road. For this it is necessary that the driving instruction is transmitted in a different way than the usual optical way. FIG. 3 shows, for comparison, driving instructions transmitted by authorized persons in a classical manner, in the present example by police forces. In the upper illustration, a so-called Winkerkelle is held out of a civilian vehicle to mean that the following vehicle should follow the vehicle 135 and possibly stop. In the middle illustration, the driving instruction is output by a short text message on a stop signal generator on the roof of the further vehicle 135. In this case, the other vehicle 135 is well recognizable as an official police vehicle.

In the lower illustration of FIG. 3, a person is depicted with a safety vest, which identifies the person as a policeman. The police officer holds a winker and simultaneously gives a hand signal to cause an approaching motor vehicle 100 to stop.

The driving instructions shown in FIG. 3 can be detected or recognized optically only with great difficulty in the present state of the art. It is therefore proposed, in addition to or as an alternative to the known signals, to transmit driving instructions wirelessly, for example by means of data radio, for the purpose of influencing a motor vehicle 100 guided independently of the driver. A control device 105 on board the motor vehicle 100 can then execute the received driving instruction itself or cause a driver of the motor vehicle 100 to do so.
